UV-K5 Version v0.3D (<- v0.3C <- From v0.3B)

UV-K5 Version v0.3D (Test Version) - Changed from Version 0.3B, 0.3C
DigiManager 0.5 -> 0.7
(Since the communication speed has changed, please delete the existing Digimanager and download it again)

This version is a test version, and if there are no major problems, only the version number will be changed and it will be re-released as 0.3P
If you want a stable version, please upload 0.3P

• Changed the communication speed between PC and UV-K5 from 115200 to 57600
  Communication between PC and UV-5K is not stable using certain programming cables (used when updating firmware)
  Internet search results showed that problems occurred at 115200 BPS for certain products.
  Among the cables I have, the Prolific product had a problem with 115200.
  Thank you to those who tested and provided reports.
  If the problem occurs again on another cable, it can be down speed to 38400 (firmware writing speed).

-When moving from 'Spectrum & Waterfall' to the marking frequency (Press Number 1 then press 2 or 3), it has been improved to operate differently depending on the Lock and Unlock of the Select Bar.
(Lock/Unlock in Select Bar can be changed by pressing and holding the 'F' button)

------------ VERSION 0.3C -------------

• AMFIX applied when receiving from Spectrum & Waterfall (Todo in 0.3B)
• Fixed issue with GPS coordinates with more than 4 decimal places in APRS (Todo in 0.3B)
• STATUS (top of screen) ICON rearrangement
• Fixed issue where the Monitor function is activated under certain conditions when Spectrum & Waterfall is closed. ( Commented by Sean, N7SIX)
• APRS, SSTV SideTone volume (Added in Version 0.3) changed ( -> 100)
• CWFM (F2A) SideTone volume changed ( -> 100)

--------------VERSION 0.3B ----------------
UV-K5 Version v0.3B (Test Version)

As announced in advance, various experimental versions will be released up to V1.0, and the source code will be registered when V1.0 is released. Until V1.0, we will only upload firmware binary files. (This version release includes version 0.1C source code)

This version is a test version, and if there are no major problems, only the version number will be changed and it will be re-released as 0.3P
If you want a stable version, please upload 0.3P

The main changes in this version are as follows.

• DIG.M (Digital Mode) menu has been added. When Digital Mode is ON, the External CW Key does not work. When using the CW Key, turn Digital Mode OFF. If the Digital Mode is changed (ON->OFF or OFF -> ON), be sure to turn the radio off and then turn it back on.
• Stand alone WSPR function has been added. Before going outside, use UV5DigManager to input WSPR information into UV-K5.
• A function to send APRS messages by connecting to a computer has been added. You can easily receive data by simply modifying the programming cable (the cable used when updating the firmware).
• The cable used in APRS is also used for connection with WSJT-X, which is scheduled to have additional features in 0.3X

TODO(0.3X) : Applying AMFix in Spectrum & Waterfall
When transmitting APRS coordinates, limit to 4 decimal places.

UV-K5 Version v0.2P

All features of Version 0.2P are specified in the Link below.
https://github.com/phdlee/uvk5cec/releases/tag/v_0.2B

From Version 0.2B, it was a version for testers, and after various opinions and bug fixes, it progressed to the final version 0.2J.
Version 0.2J had a stabilization period of about 4 to 5 days, and no special bugs were found, so Version 0.2P was released with only a name change. Several improvements to APRS will be reflected in version 0.4

As announced in advance, various experimental versions will be released up to V1.0, and the source code will be registered when V1.0 is released. Until V1.0, we will only upload firmware binary files. (This version release includes version 0.1C source code)

Please refer to the blog below for more details. Blog posting takes approximately 1-2 days.
http://www.hamskey.com

UV-K5 Version v0.2J (Changed v0.2B -> v0.2C -> v0.2E -> v0.2H -> v0.2J)

UV-K5 Version v0.2J (for test)
Changed release from 0.2H to 0.2J
1.Bug Fixed : Solved a problem that occurred when using only one digpeater
2.Reduce preamble to 130 times (100 -> 150 -> 130)
The size of the preamble is slightly different for each program and each radio manufacturer, and is handled as an option, but the optimal length is selected to save program space.

UV-K5 Version v0.2H (for test)
Changed release from 0.2E to 0.2H (The 0.2H file was deleted due to a bug (when using a single Aprs Digipeater, Please download bug fix version 0.2J)

1. Transmit only in the set area in CW mode

2. All APRS Digipeater SSIDs have been removed.
   If both AprsDP1 and AprsDP2 require an SSID, enter the 7th character from 0 to 9 to be applied as the SSID.
   ex) WIDE1 <-- No SSID
   WIDE1 0 <-- No SSID
   WIDE1 1 <-- SSID 1
   WIDE1 2 <-- SSID 2

3. For user convenience, Digipeater allows the character '-'
   The character '-' is automatically converted to space to meet the Aprs standard.
   So, you can input as follows.
   ex) WIDE1-1
   WIDE2-3

4. There was an opinion that the preamble was too small, so it was increased to about 1 second.
   I wanted to make it optional, but I made it fixed due to the remaining memory space.

5.CWM was added in addition to STS, MSG, and POS.
CWM operates identically to MSG. However, all characters from CW MSG0 to CW MSG4 are transmitted, not the AprsMSG item. The maximum is 50 characters.
However, if a '#' character is encountered, transmission is stopped.
With this, you can select and use CWMSG0~CWMSG4 in CW mode and Aprs.

CW MSG0, CW MSG1, CW MSG2, CW MSG3, CW MSG4 are in the U.INFO menu.

---

UV-K5 Version v0.2E (for test)

Changed release from 0.2C to 0.2E

1. Aprs-related order has been changed in U-INFO.
   You must re-enter Aprs-related values. I apologize to those testing this because it has to be set repeatedly.

5.Aprs DST menu has been removed.
Aprs DST has been fixed to APK5C1 in response to the opinions of those who tested it.
I tried to use APZxxx, but expermintal tags appeared in many decoders, so I configured it as AP + K5 (UVK5) + C (Firmware Version) + 1 (Index).
If you have any opinion that the Aprs DST item should not be fixed, please let me know

6.AprsDIG name changed to AprsDP1 (Aprs Digipeater 1) and AprsDP2 was added.
Please do not enter anything in AprsDP2 by default. If incorrect values are entered, APRS will not operate. AprsDP2 is Aprs expert mode.

7.If you set up AprsDP2, you can use it by adding one more Aprs Digipeater.
However, AprsDP2 does not automatically set the SSID. If you want to add an SSID to AprsDP2, be sure to configure AprsDP2 with 7 characters. The 7th character is from 0 to 9 and is used as the SSID. If SSID is not needed, set the 7th character to 0.
It is possible to add an SSID menu for Digipeater2, but I used this method because it takes about 200 bytes of memory.
A detailed description of Digipeater2 will be posted on www.hamskey.com when version 0.2P is released.
If an error occurs, delete all AprsDP2.

8. The existing AprsMSG function was to transmit the status of Aprs. I sent a message to Status.
   So, I changed the existing AprsMSG name to AprsSTS (Status)

9.The AprsMSG menu sends messages using the Aprs Message protocol.
Aprs Message must have a recipient, and the recipient can be entered in the 'DX Call' item in the U.INFO menu.

Thank you to everyone who provided various tests and comments.
All of these modifications were made based on APRS Protocol Reference Version 1.0.

UV-K5 Version v0.2C (for test)

Changed release from 0.2B to 0.2C.
In 0.2B, we fixed bugs that testers provided feedback on.
1.SSID storage problem
2. Decode error when transmitting GPS coordinates
3. Digi ID can be omitted in case it is not used -> An error will occur if omitted according to the APRS regulation document and protocol.
You can use it by setting SSID to 0.
If you don't need DigiID, set DigiID to 0.

You can update it using cec_0.2C.packed.bin

UV-K5 Version v0.2B (for test)

As announced in advance, various experimental versions will be released up to V1.0, and the source code will be registered when V1.0 is released. Until V1.0, we will only upload firmware binary files. (This version release includes version 0.1C source code)
You can update it using cec_0.2B.packed.bin

The main changes in this version are as follows.

• Reduce memory usage for CW, SSTV, etc.
• After transmitting SSTV, transmit to My call sign (at U.INFO menu)CW (as MMSSTV)
• SSTV transmission function by pressing PTT for a long time
• APRS Function - Send Position, Message (just 10 Character)
• Added APRS-related settings

Todo :
1.Separate CW Expert version (for users over 20WPM)
2.RX Gain adjustment
3.Live Seek feature improvements
Below are features that have been tested by testers but have not yet been implemented.
In particular, the CW function has been improved so that two timers monitor the user's paddling movements and detect the user's
paddling even during CW transmission. Therefore, K.PAD (Ke Paddle) cannot be used. For this reason, I plan to compile the version in two.
* CW Common Version: K-Straight, K-Paddle, External Straight, External Paddle (just IAMBIC A Mode)
* CW Expert Version: External Straight, External Paddle with IAMBIC.A or IAMBIC B

The current version will be tested for 1-2 weeks and then redistributed as stable version 0.2P If you don't want to be a beta tester, you can download 0.2P in 1-2 weeks.

Version 0.1c (January 5, 2024)

Version 0.1c (January 5, 2024)

Detailed explanations are provided in the link below.
http://www.hamskey.com

This version fixes the parts that amateur radio operators found most inconvenient.

1. Add Mhz button when entering frequency. If you want to move the frequency to 28.010, enter 28010 ( button as Mhz button)
2. Operating in Live mode when moving the frequency quickly (receiving while moving the frequency)
3. Free up some memory for future tasks
4. This version is a stable version and the source code was released together. Various experimental elements will be added from the next version, and as announced, the source code will be finalized and released upon the release of version 1.0.

you can firmware upload using cec_xxx_packed.bin file

Version 0.1b (Change only some functions for amateur radio operators to the basic functions)

Version 0.1b (January 2, 2024)

• All basic features of this source are based on egzummer's date of January 2, 2024.
• I worked on the first firmware. I did what was requested by the user. Alternatively, functions that are not greatly needed in amateur radio were changed to those that are needed in amateur radio.
• This version is stable because no major modifications have been made to the existing source code.

1. I took the source code from https://github.com/egzumer/uv-k5-firmware-custom and created a new project.
2. Change the environment so that it can be used in Visual Studio Code (win_make.bat, makefile option ...)
3. Remove some unnecessary variables for operation
4. Changed the BCL function to be selectable at the compilation stage. (Because BCL is not often used in amateur radio), If you need the BCL function, just set the compilation options. (ENABLE_BCL ?= 0)
5. Changed all band TX activation from 10 times to once (this can also be operated in the old form in the makefile) (This is because you working in the Hiddel Menu anyway)
6. The 350TX, 350EN, and 500TX functions have been changed to amateur radio bands. Even if TX 350 and TX 500 are ENABLE, they only operate under certain conditions. (Default Range Mode) , In countries where the TX function must be tested for radio use, TX on all frequencies must be within range. To receive permission for 900Mhz or 1.2Ghz, just enable TX900 and (TX126 OR TX127 - Each country has different licensed frequency bands. Just choose the band that suits you.)
